6TB storage expansion
Introduction
56 instead of 50TB are now available for the bioinformatics cluster. The tasks required to realize this extra space are:
- rescan multipath, details: multipath WWID; 36000d3100051f800000000000000016e (on mpathd)
Tools
mulipath -l will give a useful if not very understandable list of characteristics. Most important, the device: dm-6 is noted, i.e.
